HINGE.

Application filed June 1, 1915.

T0 all whom Zt may concern.'

Be it known that 1, ABNER J. WINDER, a citizen of the United States, residing at Fresno, in the county of Fresno and State of California, have invented new and useful Improvements in Hinges, of which the following is a specification.

This invention relates to a hinge and particularly pertains to a spring hinge for normally maintaining the closure to which it is attached in a closed position.

1t is the object of this invention to provide a hinge of the above character having a demountable pivot pin whereby the leaf members of the hinge may be separated when it is desired to remove the door or closure carried thereby without detaching the leaf members of the hinge from the closure or its casing. v

Another object is to provide a construction whereby the pivot pin will serve as a fastener for holding oneend of the hinge spring against movement and by which the pull o-n the spring will be transmitted to one of the hinge leaf members through the removable pivot pin.

Another object is pivot pin for spring to provide a removable hinges so formed and mounted that it may be readily removed and replaced and whereby it is rigidly held against turnable movement in relation tov one of the hinge leaf members. y

A further object is to provide aspring hinge having a demountable pivot pin and separable leaf members with an adjustable helical spring arranged to normallv dispose the hinge leaf membersin a closed positiony which embodies few partsfadapted to be readily assembled and demounted.

The invention isillustrated in the accompanving drawings in which: y

Figure 1 is a view in perspective illustrating the hinge as applied to a door and its casing. Fig. 2 is a view of the hinge as disposed in an open position showing it partly in vertical section and partly in' elevation with portions broken away. Fig. 3 is a view in horizontal section on the line 3-3 of Fig. 2 showing the'liinge leaf members as positioned at right angles to each other.

7 is a view in perspective of the demount-v able pivot pin.

More specifically, 10 indicates one of the leaf'members of the hinge which is formed with a cylindrical casing 11 on one edge thereof, the casing 11 being open at its upper end and having an inturned annular flange 12 on its lower end. rl`he casing 11 is preferably formed of a length less than the length of the leaf member 10 and arranged thereon with its upper and lower ends spaced from the upper and lower edges of the leaf member.

T he casing 11 is designed to receive a helical spring 13, the lower end of which is engaged by a collar 14 having a diameter slightly less than the inside diameter of the casing and adapted to be positioned within the latter and to seat on the flange 12. The collar 14 is formed with an opening having a ilat face 15 and which opening is here shown as semi-circular in form with its arcuate portion in vertical alinement with the inner marginal edge of the flange 12. The upper end of the spring 13 engages a sleeve 16 having an outwardly extending shoulder 17 adapted to seat on theupper end of the casing 11; the sleeve 16 thus having a lower, portion of one diameter to extend within the casing in slidable Contact therewith and having an upper portion extending` above the casing. The lower portion of the sleeve is formed with an annular channel 18 which is engaged by a set screw` 19 extending through the wall of the casing 11 by which the sleeve 16 is Iheld in position on the upper end of the casing. The upper portion of the, sleeve isr formed with a series of sockets 20 on its peripheral face for the reception of aV pointed instrument (not shown) by which the sleeve may be rotated to adjust the tension of the spring 13; the sockets 20 also serving as depressions to receive a deinountable pin 21 arranged to extend outwardly from the sleeve 16 into engagement with the leaf member 10 to hold the sleeve 16 against rotation and to retain the spring 13 under tension. The otherV leaf member 22 of the hinge is formedA with a pair of spaced lugs 23 and 24 on one edge thereof which lugs arev arranged such distance apart that the upper face of the lower lug 24 will abut against the under side of the casing 11 and the lower` ico the leaf members of gether, as shown in Y 23 is formed with a vertical bore 25 which'is relation to the leaf 22. The lower portionpof the pin 26 may be,

Vcollar 14V and lug 24 but it vits arcuate preferably circular in form for the reception of a demountable pivot pin 26 which is designed to extend through a circular opening 27 in the sleeve 16 and to project through the collar 14 and the lower end of the casing 11 into a recess 28 formed in the lower lug 24. The upper end of the pivot vpin 26 is formed -with a head 29 adapted to seat on the lug 23l and the lower end ofthe pivot pin is formed witha flat face 30v adapted to engage the Hat face 15 forming one wall of the opening through thecollar 14 and to also engage a correspondingflat face 31 forming one wall of the recess 28. When the hinge is assembled and the pivot pin 26 is in position, as shown in Fig. 2, the lower end of the pivot pin will be engaged by the lug 24 so that the pin will be held against rotation in relation to the leaf member 22 and the lugs thereon and the collar 14 will be engaged by the pin and Vheld against rotation in relation to the pin and the leaf member 22 ;V the leaf member 10 being pivoted on the pivot pin 26 to turn in of any desired shape, the essential feature' being to provide it with a flat face by which it will engage ycorresponding faces on the is preferably formed of semi-circular cross face arranged to slidably Contact the inner peripheral face of the flange 12 to forma lateral bearing for the casing 11. Y In the application andoperation of the hinge, the spring 13, collar 14 and sleeve16 are placed in position in the casingll. The lugs 23and 24 are then disposed astrideof the casing 11. whereupon the pivoty pin 26- is introduced through the opening 25 in the lugr23* and passed through the sleeve 16 and the collar-14axially of the spring 13 intoengagement with the lug 24, as shown in Fig. 2. The spring 13 is then tensioned by rotating the sleeve 16 by asuitable implement- .and whenthe desired tension is obtained the pin521 is inserted in the socket 20, as shown in- Fig. 3, toY retain the spring under tension; The leaf members 10'and 22 may then be attached to a casing 32 and a door 33 by means Y of screws 34 or other suitable fastenmgs, as

shown in Fig. 1, or the leaf members may be separated and secured in place on the casing and door before assembling. i

lVhenit is desired to vdemount the door 33 the spring 13'is untensioned by removing the pin V21.I whereupon the pivot pin 26 may b e withdrawn,,thusseparating the leaf members 10 and 22 `of the hinge, thereby permitting the removal of the door without detachsection withV ing the leaf members-from the casing and: @id l Y Iclaim:
